Tree Decay Detection Using Resistograph Microdrill

Decay detection is sometimes necessary where suspected decay or hollowing cannot be sufficiently assessed by visual means. Data provided by specialist decay detection equipment enables a more accurate assessment of internal decay and the likelihood of tree failure.

For decay detection, we use the latest Resistograph Microdrill (IML Resi-PD400), which accurately measures the drilling and feed resistance along a needle when inserted at a constant rate into a tree. This enables small changes of internal wood structure to be detected. The data is recorded digitally, and findings are illustrated with a coloured graph in the report. The Resi-PD400 is a versatile piece of equipment that can be used on the ground to assess the trunk and large structural roots, or higher up in the tree as part of an aerial/climbed inspection.

We provide decay detection to customers throughout North London, Hertfordshire, Buckinghamshire and the surrounding areas. If you have a tree that is at risk of decay, give our team a call. We will accurately identify any issues and determine the best course of action for your tree.
